Storage shelf unit for storing at least one stored goods carrier and method for recording a stock of a storage shelf unit

Abstract

The invention relates to a storage shelf unit ( 10 ) with a plurality of carrier supports ( 12 ) disposed one above the other for supporting stored goods carriers ( 20 ) that can be transported by means of an automatic transport device ( 14 ), with at least one loading and retrieval opening ( 16 ) for delivering and retrieving the stored goods carrier ( 20 ). An image recording unit ( 40 ) is disposed at an upper side ( 18 ) of the loading and retrieval opening ( 16 ) for this purpose. The image recording unit ( 40 ) is attached to a moving device ( 30 ) that can be moved in a horizontal direction (X).

The invention claimed is: 
     
       1. A storage shelf unit comprising:
 a plurality of carrier supports disposed one above the other for supporting stored goods carriers, 
 an automatic transport device for transporting the stored goods carriers, 
 at least one loading and retrieval opening for delivering and retrieving at least one of the stored goods carriers, 
 an image recording unit disposed at an upper side of the at least one loading and retrieval opening, 
 a lighting device for highlighting a region of the stored goods carrier that has been recorded by the image recording unit, and 
 a moving device configured to move in a first horizontal direction and a second horizontal direction, wherein the image recording unit and the lighting device are attached to the moving device. 
 
     
     
       2. The storage shelf unit according to  claim 1 , wherein the image recording unit is oriented substantially perpendicularly to a storage surface of the stored goods carrier for taking an image of the storage surface. 
     
     
       3. The storage shelf unit according to  claim 1 , wherein the moving device is disposed on rails disposed orthogonally to each other, wherein the moving device is configured to move along the rails by a motor. 
     
     
       4. The storage shelf unit according to  claim 1 , wherein the image recording unit has an objective lens with a fixed focus. 
     
     
       5. The storage shelf unit according to  claim 4 , wherein the lighting device illuminates the first region of the storage surface by a red light for highlighting the first region, or by a white light for illuminating the first region. 
     
     
       6. The storage shelf unit according to  claim 1 , wherein an image evaluation device, which takes the image recording unit images of several regions including at least the first region and a second region from different positions of the moving device and combines them into a complete image. 
     
     
       7. A method for recording a stock of a storage shelf unit, the storage shelf unit comprising:
 a plurality of carrier supports disposed one above the other for supporting stored goods carriers, 
 an automatic transport device for transporting the stored good carriers, 
 at least one loading and retrieval opening for delivering and retrieving at least one of the stored goods carriers, 
 an image recording unit disposed at an upper side of the loading and retrieval opening, 
 a lighting device for highlighting a region of the stored goods carrier recorded by the image recording unit, and 
 a moving device that can be moved in a first horizontal direction and a second horizontal direction, wherein the image recording unit and the lighting device are attached to the moving device, the method comprising the following steps: 
 a. positioning a stored goods carrier in the loading and retrieval opening of the storage shelf unit; 
 b. moving the image recording unit and the lighting device attached to the moving device over a region of the stored goods carrier into which stored goods are placed or from which they are retrieved, the image recording unit and the lighting device move over the stored goods carrier located in the loading or retrieval opening; 
 c. taking an image of the region of the stored goods carrier; 
 d. storing, processing and evaluating the image. 
 
     
     
       8. The method according to  claim 7 , wherein the image recording unit records images by an unvarying focus or has an unvarying orientation for taking the image. 
     
     
       9. The method according to  claim 7 , wherein the image evaluation device crops the recorded image of the region in such a way that at least one depositing region is shown in the recorded image. 
     
     
       10. The method according to  claim 9 , wherein the image evaluation device determines a complete image of the stored goods carrier by combining a plurality of pictures of the depositing regions. 
     
     
       11. The method according to  claim 10 , wherein an unoccupied depositing region on the stored goods carrier is visually marked in the complete image of the stored goods carrier. 
     
     
       12. The method according to  claim 7 , wherein stored goods in the depositing region are identified by image recognition and information on the stored goods is displayed on a display unit. 
     
     
       13. The method according to  claim 12 , wherein inventory records are automatically prepared or updated subsequent to the loading and/or retrieval of stored goods.
